h1. ERPNext 14

long term goal is to run ERPNext in a podman-pod. Maybe this can be a first stepping stone:

https://piotrkrzyzek.com/how-to-setup-self-host-erpnext-in-docker-without-treafik-nginx-only/

until then we use Bitnami VMs.

h2. Bitnami based on Debian 11

out of the box ERPNext is installed. This describes what else can/needs to be done:

h3. convert VirtualBox-ova to be used with KVM

untar @.ova@

<pre><code class="shell">

tar xvf bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami.ova

</code></pre>

convert @.vmdk@ to @.qcow2@ while showing 'progress'

<pre><code class="shell">

qemu-img convert -p -f vmdk -O qcow2 \

  bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami-disk1.vmdk \

  bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami-disk1.qcow2

here is again some 'magic', there is no MTA available. So any output from the cron-job gets discarded.

use the upper construct to debug and append the output to @/home/bitnami/erpnext-backup.log@
